An intensive deforestation is taking place in North of Thailand. Seua (Sorapong
Chatree), young man, is back to his native city and is looking for a job. He met Duang, a
former girlfriend. Priaw, Duang's brother, drives him to a neighbouring city, Mae Sot,
where job opportunities are soaring. Seua meets Pop, an old friend, in order to get job
recommendations. Seua is married but he comes alone. They have a drink in a bar.
Two interesting characters are working in the bar, i.e. lady Toi (แม่เพลิงไฟ) and ladyboy
(กะเทย) Aree, who is a musician and singer. Pop is shot while they are having a drink. A
Police inspector (สารวัตร) is investigating the murder but no clues can be found regarding
the murderer and cause. It seems to be linked to a corruption and bad influence case.
Kamsaen, rich and influential man (พ่อเลี้ยง) , has a beautiful daughter called Kamyat. Pop
was a family member but he was not well appreciated as he tried to seduce Kamyat.
Seua tries to meet Kamsaen but to no avail. Some ruffians sent by Sinkon, Kamsaen’s
close assistant, try but fail to drub Seua. Truth has to be hidden and it is a strong
message that Seua should stop investigating on Pop’s death. The bar manager is shot
also. Seua is seriously beaten at the head as he refuses to stop investigating. While
driving, Sinkon is also shot by the hitman. A former policeman, Natheum, passing by,
sees the hitman’s face. All witnesses are killed one by one. Illegal forest concessions
(ตัดไม้เถื่อน) business is suspected. Threatening letters are now received by Seua. A plan is
prepared with the police inspector. They break over the ruffians directly inside the
forest. Shootings happen between police and the ruffians. They release Kamsaen and
his daughter held prisoners inside a hut. The ruffian leader succeeds to escape and is
still unknown. Natheum is Seua's old friend. While having a drink in the bar, he
recognizes Aree as the hitman. Kamsaen has been simulating his capture and is in fact
the real headmaster. Toi is his mistress. Kamsaen is killed while trying to resist to the
police. Seua, carrying a Magnum 357 gun, revenges his friend Pop by shooting Aree.
The magnum 357 is certainly influenced by inspector Harry movies with Clint Eastwood.
This movie is a typical action movie from decades 1970s-1980s and features the finest
Thai actors and actresses.
